Paranormal Challenge premiered with "Rolling Hills Asylum" - a battle of the sexes between two teams. Following a few more episodes, teams improved and provided better evidence and teamwork, allowing for some close calls in choosing a winner. During "USS Hornet", Soul Seekers captured profound evidence of a spirit channeling its energy through a MEL Meter using morse code. It was later determined to be a type of encrypted message used by US military during battles. Challenge ended with "Jerome Grand Hotel", further explaining that teams need to make sure they do not contaminant their own evidence, as past teams had done.
